Simplifying Complex Numbers
In this lesson, we learn how to simplify complex numbers by taking out the negative sign and using i for imaginary. By finding the greatest square number that goes into the radical, we can simplify our radicals by taking it out. We then combine the like terms and simplify our final answer.
How to simplify complex numbers
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.

This video shows how to add and subtract two expressions that have a negative value under the radical symbol. It assumes the viewer knows that the square root of -1 is i.
